Stop using legacy formatting for response patterns

[falcon-git]

Delimiters like [,] stem from Scorm, and doesn't feel right for xAPI. xAPI should start using json instead.

i.e. "{case_matters=false}blue[,]Cloud[,]black"

Would probably be better described as:

{ caseMatters: false, correct answers: [ ['blue'], ['Cloud'], ['black'] ] }

Better because you wouldn't have to create custom code to parse the data, and it would be easier to add more properties later like support for multiple correct alternatives.

This issue is for xAPI 2.0. I'm unable to add the 'major' label it seems, so I hope someone else can do that.
